FAQ about Asus K501LX RAM
How much RAM can I add to the Asus K501LX?
You can add up to 8GB in the single accessible slot. The laptop has 4GB soldered on the motherboard that can't be changed, so maximum total is 12GB.
What type of RAM does the K501LX use?
It uses DDR3 SODIMM modules - the smaller laptop memory sticks. Make sure to get DDR3, not DDR4 or DDR5.
What speed RAM should I buy?
Get 1600MHz DDR3 (also called PC3-12800). The laptop will work with slower speeds but you won't get the best performance.
Can I upgrade both RAM slots?
No, only one slot is accessible. The other has 4GB permanently attached to the motherboard. You're stuck with that 4GB.
Is it worth upgrading from 4GB to 12GB?
Definitely. Going from 4GB to 12GB makes a huge difference for multitasking, running multiple browser tabs, and general system responsiveness. It's one of the best upgrades you can do.
Will faster RAM like 1866MHz or 2133MHz work?
It'll work but will automatically slow down to 1600MHz to match what the laptop supports. Save money and just get 1600MHz.
